Vivaspin ® 500 centrifugal filter units offer a simple, one step procedure for sample concentration with starting volumes up to 500 µl. They can effectively be used in fixed angle rotors accepting 2.2 ml centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber (US 5,647,990), minimises membrane fouling and

Rainin Pipette Tips. Rainin pipette tips fit most pipette brands, including a pipette tip for Rainin, Gilson, Eppendorf, Sartorius (BioHit), Thermo (Finn), and VWR pipettes. Made from 100% virgin polypropylene in a fully automated, Class 100,000 clean room facility, Rainin tips provide excellent clarity and flexibility for accurate touch-off.

Nest syringe filters have pore size either 0.22μm or 0.45μm, and diameter 13mm or 25mm, with membrane materials either with PES or PVDF membranes. For sample volumes of 2mL to 100mL Retention volume <115µL Maximum operating temperature: 100°C autoclave at 125°C

Syring Filter found in: Syringe Filters, Syringe Filters, Plastic Syringe Filters, Acrodisc® Syringe Filters, 25mm Syringe Filters, Syringe Filters, 13mm..

The single channel model is available in fixed volume and adjustable (digital) volume models in volume ranges from 0.1µL to 10mL. The multichannel model is available in 8- or 12-channels in volume ranges from 0.5µL to 300µL. Product Features: One-handed volume adjustment with brake to protect against accidental volume changes

NOTE: To reduce hold-up volume, care should be taken to minimize tubing length. If necessary, the reservoir should be tilted toward the inlet tubing to assure that all the sample or buffer is transferred to the Amicon stirred cell during processing. The selector valve was set to “Gas” mode (gas spool in) Stirring was initiated at 200 rpm.

atmospheres, where targeted fiber concentrations are much less than 0.1 fiber/cc, use larger sample volumes (3000 to 10000 L) to achieve quantifiable loadings. Take care, however, not to overload the filter with background dust. If ≥50% of the filter surface is covered with

The normal serum creatinine reference interval does not necessarily reflect a normal GFR for a patient. Because mild and moderate kidney injury is poorly inferred from serum creatinine alone, NIDDK strongly encourages clinical laboratories to routinely estimate glomerular filtration rate (GFR) and report the value when serum creatinine is measured for patients 18 and older, when appropriate

Jun 11, 2021 · Membrane filters have a known uniform porosity of predetermined size (generally 0.45 µm ) sufficiently small to trap microorganisms. Using the membrane filter technique, sample is passed through the membrane using a filter funnel and vacuum system. Any organisms in the sample are concentrated on the surface of the membrane.
